This forum is dedicated to discussions pertaining specifically to the Motorola ASTRO line of radios (those that use VSELP/IMBE/AMBE), including using digital modulation, digital programming, FlashPort upgrades, etc. If you have general questions please use the General or Programming forums.
The 5 keystroke press on power up works on the XTS5000. I did first thing after receiving it. What is really interesting is that since the radio is flashed for ASTRO trunking it has an IMEI number as well as the serial. Radio has 700 and 800 mhz test frequencies also.
IMEI number is a unique identifier used in cellular networks like GSM etc. for each subscriber unit. I suppose the 9600 baud systems use the IMEI in conjunction with radio ID's. This would serve to make it more difficult for someone to gain Xmit access by simply cloning a radio ID.
